What word do we use to describe the movement of a moon about a planet?
The movement of a moon around a planet is described as its "orbit." This term refers to the gravitationally bound path that the moon follows as it revolves around the planet. Orbits can vary in shape and size, depending on the gravitational forces involved.
Why are forces balanced or unbalanced on planets?
The forces on the planets are not balanced. The gravitational force between the sun and each planet is what keeps the planet in orbit around the sun. If the forces on a planet were balanced, then the planet would sail off in a straight line, and would never be seen or heard from again.
The movement of a planet around the sun?
The name of the path a planet occupies in its movement around the Sun is called an orbit. The shape of the path is an ellipse, with the Sun at the focus. Due to the inverse-square rule of gravity, the speed of movement is greater in orbits closer to the sun, slower for more distant orbits.
Is the movement of earth and other planet around the sun?
Revolution.
How do balanced forces help the planets?
The forces on the planets are not balanced. The gravitational force between the sun and each planet is what keeps the planet in orbit around the sun. If the forces on a planet were balanced, then the planet would sail off in a straight line, and would never be seen or heard from again.
What causes constant movement of planet around the sun?
the sun's gravitational pull
What forces act to hold a planet in orbit around the sun?
The gravitational force between the planet and the sun is what holds the planet in orbit around the sun. This force keeps the planet moving in a curved path around the sun, in balance with the planet's inertia.
What does revolve mean in outer space?
Earth revolves around Sun. Or Earth orbits around the Sun. It means that Earth goes around the Sun (circles around the Sun if you want although the trajectory is not exactly a circle but an ellipse).
What is a planet's revolution?
A planet's revolution is its orbit around the sun. A planet's rotation is its movement about its axis. For example, the Earth's revolution around the sun takes 365.26 days, and its period of rotation is 24 hours.
What is a year in terms of planet movement?
The time it takes to orbit around the sun once.
What movement of the planet makes one year as a unit a time?
a revolution, that is, the amount of time it takes the planet to complete its journey around the sun.
What current are results of the movement of the sun and the moon?
The tides around the planet. The Sun and moon both exert gravitational pull on the water on our planet.
